To all whom it may concern:

- Be it known that l, Gannon WASHINGTON LEnKnnn, a citizen of the UnitedStates, and a resident of Indiana, in the county of lindiana and Stateof Pennsylvania, have invented a new and Improved Wall Construction, ofwhich the following is a. full, clear, and exact description.

This invention relates to building construction and has particularreference to the formation of walls out of precast or otherwise formedbuilding units.

Among the objects of the invention is to provide a means or method forbuilding a wall, using for such purpose mainly hollow bricks of auniform standard type or form having straight parallel walls and withone v or more openings entirely through the cen ter from end to end, andat the same time provide a means for forming the corners, trimmings,arches or the like, of solid bricks of a composition and sizecorresponding to the outside appearance of the hollow bricks.

Without limiting the scope of this patent unnecessarily as to theparticular type or design of hollow bricks to be used, I may state, foran illustration of a suitable hollow brick, that the one which I haveused extensively in the practice of this invention is the one describedand claimed in mycopending application filed August 21, 1915, Serial No.46,744. The essential characteristic, however, of the hollow brick isthat it shall present or have an outside appearance as to composition,color, or lines of pointing, to correspond with standard sizes orcompositions of common solid bricks.

With the foregoing and other objects in View, the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed herein, still for the purpose of illustratinga practical embodiment thereof reference is had to the accompanyingdrawings, inwhich like reference characters designate the same parts inthe several views, and in which-- Figure 1 is a perspective view of afragment of a wall made in accordance with this invention, the mainportion of the wall being composed of hollow bricks, while the cornersand trimmings are of solid bricks, both types of bricks having the somedesignat the surface; and. Fig. 2 is a vertical sec-' Specification ofLetters Patent.

tional View of a portion of the same wall on a plane parallel to thefront'surface thereof.

Referring now more particularly to the of a length corresponding to thatof one of the solid bricks 11 and of a height corre; sponding to that oftwo solid bricks with an intermediate layer of mortar 12. Also thehollow'bricks are grooved or scored longitudinally along their sidesmidway of their height, as indicated at 13, to receive a line orpointing of mortar resembling the mortar 12 in outside appearance.

In the rapid and economical construction of a building wall, it isessential that the hollow bricks shall all be of the same type, and forthe formationpof a hollow wall it is also essential that the hollowspaces in the hollow bricks must extend fully from one end to the other,whereby the air passages are continuous throughout? series of all of thehollow bricks arraTnged end to end. It will be appreciated, therefore,that with the foregoing conditions it is impossible to form a corner ofthe wall or any other irregularity in the wall with any of the ends ofthe hollow bricks exposed.

By reference now more particularly to Fig. 2 it will be appreciated thatthere is a decided advantage in the method of wall construction that Iemploy and describe herein, the same involving the use of solid bricks11, of the same standard dimensions as represented by the grooving orscoring on the sides of the hollow bricks, for the for1nation of thecorners 14 bounding the ends of the wall or the side edges of a niche.The arch 15 also is preferably built of solid bricks 11'.

A wall built in accordance with this method has all the advantages ofordinary hollow walls, practically the full strength of walls built ofsolid bricks, since the corners or other exposed parts that are mostsusceptible of damage or crushing are of solid bricks, and may be builtat a much lower cost than other walls because of the uniformity of thematerial and the rapidity with which the building elements may be laid.The mason or bricklayer can lay a wall of this character moreexpeditiously than of solid bricks for the reason that the principalelements of the wall being hollow and of a larger volume than theindividual solid bricks, he, in handling one of the hollow bricks exertspractically no more eflort or time than in the laying of a single solidbrick, and obviously accomplishes a larger result. Furthermore, in theformation of a wall in which only hollow bricks are used, special formsmust be relied upon for the irregularities or corners of the wall.Special hollow bricks are always vastly more expensive than standardhollow bricks having straight passageways from end to end, not onlybecause of the increased difiiculty in the formation of each of suchspecial forms, but more so because of the fact 7 that so many differentspecial forms are required, whereas, where the solid bricks may berelied upon for the formation of the cor: ners and other irregularities,there is practically no Waste of time and the operation is Copies ofthis patent may be obtained for five cents each, by addressing thecarried out at a minimum expense for material and labor.

In a composite building wall, the co1nbiv nation of a plurality ofhollow bricks for the main portion of the wall, a plurality of solidbricks for the vertical edges ofthe Wall, and courses of mortar ofuniform' thickness arranged between adjacent bricks of both species, thehollow bricks being of a height exactly equal to a plurality of solidGEORGE WASHINGTON Witnesses: v
